THERMOMETER-CASE.

SPECIFICATION forming part of Letters Patent No. 759,761, dated May 10, 1904.V l

Application le. May 13, 1903.

To LZZ whom. it may concern:

Beit known that I, HERMANN A. SIEVERT, a citizen of the United States, and a resident of Fort Wralla Walla, in the county of Walla Walla and State of Washington, have invented new and useful Improvements in Thermometer-Cases, of which the following is a full, clear, and exact description.

My invention relates to certain novel and useful improvements in an antiseptic thermometer-case especially designed for the use of physicians and surgeons.

Primarily I have in view as an object providing a case adapted to contain an antiseptic liquid within which the thermometer is at all times bathed when in the case, the construction of my case being such that the thermometer may be withdrawn therefrom while the` case is in any position.

Afurther object of the invention is to construct the article in such manner that the liquid therein will not run from its containingtube when the case is placed 4on its side or turned to any position other than upright.

With these and other objects of a similar nature in view the invention consists in the construction, combinations, and arrangement of parts, as is described in this specification; delineated in the accompanying drawings, and set forth in the appended claims.

Reference is to be had to the accompanying drawings, forming a part' of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical sectional View of a case embodying my improvement and taken on the line 1 1 of Fig. Q. Fig. 2 is a transverse sectional View taken on the Fig. 3 is a View in elevation of a perforated metallic sleeve adapted to surround the thermometer when the latter is in the case, and Fig. 41. is a vertical longitudinal sectional view taken through a thermometer-case embodying another form of my invention.

Referring' now to the accompanying drawings in detail, 5 designates an outer casing composed of any metal, such as aluminium, or of rubber or other material, such casing hav- Serial'No. 156,920. (No model.)

annular flange or shoulder 9 blown or formed thereon, this flange or shoulder acting as a support or rest for a rubber gasket 10, the upper portion of said gasket being threaded to screw into a similarly-threaded body portion 11 of the outer casing 5. The opening or aperture formed centrally in the gasket is of suliicient size to frictionally grip and retain the metallic sleeve 13., which is `,passed therethrough, the top edge of said sleeve being normally arranged on a level with the top surface of the gasket, a number of perforations or apertures 141 being formed in the tube to permit the free access of the antiseptic to the upper outer surface of the thermometer, as shown in Fig. 3.

Extending' circumferentially of the outer wall of the casing and at a point below the threads 11 is a series of threads 15, which coact with a similar series of threadsl, formed on the interior wall of the enlarged portion 17 of the cap 18. This cap 18, which lits over the casing 5, has secured to the inside thereof by means of a coiled tension-spring 19 a disk 20, of rubber' or any suitable material, the intention being' that when a thermometer is inserted within the case and the cover is screwed on the casing the disk will press on the edge of the thermometer, the spring allowing said disk to bear upon thermometers of varying length. At the bottom of the glasstube 8 is arranged a small rubber buffer 21, having a slight cavity or depression Q2 formed in the top surface thereof to receive the end of the theromometer A, the intention being that the buffer shall prevent the breaking' of the thermometer by coacting with the disk to prevent the movement of the thermometer in the case when the latter is subjected to jars or shocks. The glass tube may be iilled with any antiseptic liquid, (shown at Bg) but I prefer to use formalin, as I have found the latter very desirable for this in such manner that it will cover the thermometer up to the height of the rubber gasket, suoli thermometer therefore being to all intents and purposes completely bathed in such antiseptic liquid.

A slightly-modiiedform of thermometercase is shown in Fig. 4, and for many purposes this construction will be found very desirable. In said figure the outer casing is indicated by b, such casing having thereon a longitudinal rib or bead 5 similar to the rib or bead 5u, and within the casing is soldered or otherwise suitably secured a thimble or stopper a, the lower end portion of said stopper being provid ed with vertically-extending incisions or V-shaped cuts 10b. Formed integralwith the stopper and arranged concentrically within the same is a vertical sleeve 13, adapted to permit of the passage of the thermometer into the casing, the sleeve being' of such a size that the thermometer fits snugly in the ,same and is prevented from being injured by wabbling about in the case. The upper end of the thimble or stopper 10, which protrudes some distance beyond the top of the casing, is threaded, as at 15, such threads being adapted to coact with or screw into the threaded interior wall 16zt of the casing-cap 18, which cap has arranged therein a coiled spring 198L and a disk 20a, attached at the end thereof, these last-mentioned two parts being the same as the coil-spring 19 and the disk 2O and performing the same functions-that is to say, they bear down upon the upper end of the thermometer and hold the same against vertical movement within the case.

It will be observed that I have designed a thermometer-case which completely protects the thermometer from shock and jars and which when filled with formalin is thoroughly antiseptic.

It is to be noted that the longitudinal slots" in the metal case or covering within which the glass tube is arranged permits the height of the liquid in such tube to be observed.

While I have shown and herein described one particular embodiment of my invention, it is of course to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in certain respects without departing from the essential features of the invention or sacrificing any of the advantages thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A thermometer-case, comprising an outer casing, a sleeve arranged within said casing, a gasket supporting said sleeve, a cap for the thermometer-case, and yieldable means carried by said cap and designed to bear upon the top of a thermometer Within the casing for holding the thermometer against vertical movement, said means including a bearingdisk, and a spring connection between the disk and the cap, substantially as set forth.
